This Handbook provides an overview of federal patent and trademark law. Information discussed includes types of patents and trademarks, duration of registration, requirements for obtaining, a guide to the application process, protecting your patent or trademark, and much more in 18 pages of materials.
This page provides information on the types of patents and types of patent applications, and the examination process. The purpose of this guide is to provide you with basic information about filing a utility patent application with the USPTO.Online filing for Trade Names and Trademarks has been fully implemented and PDF forms are no longer accepted. You can sell your product for up to one year and then file a patent application with the United States Patent and Trademark Office. You may apply for a patent and sell your product to a buyer without licensing any rights (to your future patent) to the buyer. It is quasi impossible to sell a provisional. First, do the claims and file the patent. See the list of exemption codes below. The key to your question is about the selling 3-4 years before filing for a patent. The onsale bar is part of Section 102 within patent law that can prevent an invention from being patented if it was sold prior to patent filing.
